Install the meter
According to the diameter
of the tube, the choice is
whether you need a rubber
clamp ring and model
(Applicable to handle
specifications: φ22.2, φ
23.4, φ25.4, Φ31.5),
after the bracket and the
instrument are installed,
the rubber clamp ring is
inserted into the bracket as
shown in the figure position
of the wrist so that the
bracket aligns the notch of
the wrist with the notch of
the rubber clamp ring.
Turn the auxiliary switch on
the wrist and put it on the
handlebar for proper
operation. Adjust the angle
of the auxiliary switch to
make the switch easier to
see and operate when
riding. (Suitable for
handlebars with an outer
diameter of Φ22.2mm.
Use an Allen wrench to fix
and tighten the handlebar
fixing screws in the
direction shown in the
figure.
